High-TC cuprate superconductors' growth conditions and their incompatibility with some of the most standard nanofabrication approaches make their large-scale integration with 2D materials (such as graphene, transition metal dichalcogenides, and other Van der Waals materials) much more difficult than for conventional, metallic superconductors. Here, we address this challenge and develop an approach based on pulsed laser deposition that allows the growth of the 2D semiconductor MoS2 on the archetypal high-TC superconductor YBa2Cu3O7−x. This yields functional heterostructures in which the individual constituents' properties are preserved and that show superconducting coupling across their interface. The developed approach paves the way for large-scale 2D semiconductor co-integration with high-TC superconductors toward the study and leverage of the superconducting proximity effect in hybrid devices.

MoS2 在高 TC 超导 YBa2Cu3O7 上的大规模集成，用于实现 Josephson 器件


高 TC 铜酸盐超导体的生长条件及其与一些最标准的纳米制造方法的不相容性，使得它们与 2D 材料（如石墨烯、过渡金属硫化物和其他范德华材料）的大规模集成比传统的金属超导体要困难得多。在这里，我们解决了这一挑战并开发了一种基于脉冲激光沉积的方法，该方法允许 2D 半导体 MoS2 在原型高 TC 超导体 YBa2Cu3O7−x 上生长。这产生了功能性异质结构，其中保留了各个成分的特性，并在其界面上显示出超导耦合。开发的方法为大规模 2D 半导体与高 TC 超导体的共集成铺平了道路，以研究和利用混合器件中的超导邻近效应。
